Lieutenant Hunt faces off with his arch rival from another precinct while investigating a bank robbery with international connections, on ABC's Life on Mars.

The critically acclaimed series returns on a new night - Wednesday, January 28 - following ABC's hit series, Lost.

A longstanding competition between Lt. Hunt and the detectives of the 1-2-5 and Lt. Anthony Nunzio and his men of the 1-4-4 heats up when the Russian mafia appears to be linked to a bank robbery. The investigation becomes a furious contest of one-upmanship between the two squads. A nine-year-old boy at the crime scene possibly holds the key to cracking the international case, which has Hunt, Sam, Ray and Chris looking over their shoulders not only for possible suspects, but for rival detectives as well. Meanwhile a young, attractive social worker involved catches Sam's eye and he his hooked, on Life on Mars, premiering on its new night, Wednesday, January 28 (10:02 to 11:00 pm, ET) on ABC Television Network.
